The National Center for Atmospheric Research thermosphere-ionosphere general circulation model has performed a series of self-consistent calculations of the thermosphere/ionosphere structure for a variety of geophysical conditions. The model simulates March, June, and December periods for solar cycle minimum and maximum for three levels of geomagnetic activity representing quiet, moderate, and disturbed conditions. The calculations include predictions of N2, O2, O, N(4S), N(2D), NO, N2+, O2+, O+, NO+, and N+, along with the ion, electron, and neutral temperatures and the three components of the neutral winds. The model simulations are available from the authors or through the Coupling, Energetics, and Dynamics of Atmospheric regions database at NCAR. ¿ American Geophysical Union 1994
